Abstract

It provides a reinforcing bar binding machine capable of surely wrapping and binding a wire to a binding object. The reinforcing bar binding machine (1A) includes a magazine (2A) in which two wires (W) are housed so as to be drawable, a curl guide unit (5A) which winds the arranged wires (W) around the reinforcing bar (S), by the operation of feeding the parallel wires (W) at the curl guide unit (5A) to wind around the reinforcing bar (S), a wire feeding unit (3A) which to wrap around the reinforcing bar (S) with the wires (W) wound around the reinforcing bar (S), and a binding unit (7A) which twists a intersecting portion between one end side and the other end side of the wire (W) wound around the reinforcing bar (S).

Claims3

Dependent claims

A binding method comprising:

feeding two or more wires housed in a housing, in parallel;
winding the two or more wires in a loop around a binding object;
and
gripping and twisting the two or more wires wound around the binding object,
the method further including, during at least a portion of feeding of the wires between a location of the housing and a location at which the two or more wires are wound around the binding object, restricting movement of the two or more wires in a direction orthogonal to a feeding direction and restricting movement of the two or more wires relative to each other using at least one restricting unit, and wherein the restricting unit comprises an opening through which the two or more wires pass together, and wherein the opening includes a first dimension in a first direction orthogonal to the feed direction and a second dimension in a second direction orthogonal to both the first direction and the feed direction, and wherein the first dimension is larger than twice a diameter of one wire and the second dimension is less than twice the diameter of one wire.
